Aircraft funnel slat system

Abstract

Aircraft air funnel slat system of this invention for increased lift to aircraft wings and rotors comprises a pair of symmetrical and retractable slats or flaps or planks or other similarly shaped strong rigid and light weight rectangular members angled above the leading edge of aircraft wings so as to form a funnel over each wing so as to provide increased airspeed above the wing and increased lift from below the wing, which in turn greatly reduces the take off and landing distance so as to result in V/STOL aircraft.

The Inventor claims: 
     
       1. An aircraft air funnel slat system for increased lift to aircraft wings each having a leading edge comprising a pivot-able slat positioned over and above each wing so as to form a funnel between said slat and said wing and wherein said slat is adjustable from a position `parallel to said wing` to `tangentially touching said wing` and wherein said slat is in the shape of an airfoil and wherein said slat pivots about the leading edge of said slat. 
     
     
       2. The aircraft air funnel slat system of claim 1 wherein said pivot-able slat length is from ten percent to ninety percent of the longitudinal wingspan and wherein said slat width is from ten percent to ninety percent of the width of said wing.
